Patent CA-2333721-A1 (CA)
Inventor: YEE PETER P
IPC: H01J27/20
Filed: 2000-03-15
Abstract: An ion source (108) for use with an ion trap mass spectrometer (120). The ion source includes an electron source which produces a stream of electrons. The electrons are injected into an ionization chamber by the action of a repeller plate (104) and electron lens (106). Inside the ionization chamber, the electrons interact with a gas-phase sample to produce sample ions through the electron ionization process, or with a reagent gas to form reagent ions as part of a chemical ionization process. The sample ions produced are extracted from the ionization chamber by the action of an ion repeller (112) and an ion lens (105). The potentials on the electron repeller and lens, and ion repeller and lens are controlled to direct the electron stream away from the ionization chamber or to direct the sample ion beam away from an ion trap at the appropriate times during measurement of the sample ions.

Abstract: In a method of making rolls or strips of material having no flaws except joints of supply of material, such as a roll of fabric is inspected for flaws.  If any flaws are discovered portions of the material containing the flaws are cut away. The material is attached together after each portion is removed to create a joint for each reattachment. The portions that are cut away are sized so that the joints will be separated by a multiple of a selected distance from one another. The resulting material can then be fabricated into a panel of window covering material in which all the joints are co-linear along a perpendicular to the surface of the material. The joints are positioned so that they will be on a cut line for subsequent processing. In one embodiment the material is wound into a tubular structure that is cut along the joints to form a panel of window covering material.

Patent CA-2360785-A1 (CA)
Inventor: SPRUNK ERIC J
IPC: G06F21/24
Filed: 2000-01-28
Abstract: Multiple public/private key pairs of varying levels of security are used to provide a high level of security while still allowing fast processing of encrypted information. The lower-security level includes keys which are small in length, which are changed relatively often, and which require less or fewer resources to implement their functions (130), (134). When it is required to change key pairs of low security, a key pair at a higher security level (i.e, longer length keys) than the lower-security level keys is used to transfer the new lower-security public keys to devices using those keys. The higher-security keys can, in turn, be changed at a frequency lower than the lower-security keys. The higher-security keys require a higher level of resources to perform their coding operations (120), (124). This approach of using keys of escalating levels of security to replace lower-security keys, where the higher-security keys require more resources, are more secure, and are replaced less often than the lower-security keys, can be followed as many times as is desired to create a hierarchy of public key uses with the result that the lower-security operations can be performed quickly while the overall system security is high.
